Organic Light Emitting Display

摘要

An organic light emitting display comprises a display panel having a plurality of pixels, a gate drive circuit that drives scan lines and emission lines on the display panel, and a data drive circuit that drives data lines on the display panel, (n−1)th and nth pixels arranged in a row, a transistor array having a driving transistor, a sampling transistor, and a first initial transistor, and a capacitor connected between an initial voltage input terminal and the sampling transistor. A gate electrode of the first initial transistor for initializing the driving transistor of the nth pixel is connected to a scan line in the (n−1)th pixel.
